A MINIMAL PLANAR POINT SET CONTAINING A DISJOINT TRIPLE OF A 3-HOLE, A 4-HOLE AND A 5-HOLE
A subset of a finite set of points in the plane is called an empty convex polygon or a hole if it forms the set of vertices of a convex polygon whose interior contains no points of the set. Let be the smallest integer such that any set of points in the plane, no three collinear, contains a k-hole, an l-hole and an s-hole, whose convex hulls are disjoint. In this paper, we show that
convex hull, convex polygon, empty convex polygon, disjoint, hole.
